The report gives a defining description of the programming language
Scheme.  Scheme is a statically scoped and properly tail-recursive
dialect of the Lisp programming language invented by Guy Lewis
Steele&nbsp;Jr. and Gerald Jay&nbsp;Sussman.  It was designed to have an
exceptionally clear and simple semantics and few different ways to
form expressions.  A wide variety of programming paradigms, including
functional, imperative, and message passing styles, find convenient
expression in Scheme.</p>
<p>
This report is accompanied by a report describing standard
libraries&nbsp;[<a href="r6rs-Z-H-21.html#node_bib_24">24</a>]; references to this document are
identified by designations such as &#8220;library section&#8221; or &#8220;library
chapter&#8221;.  It is also accompanied by a report containing
non-normative appendices&nbsp;[<a href="r6rs-Z-H-21.html#node_bib_22">22</a>].  A fourth report gives
some historical background and rationales for many aspects of the
language and its libraries&nbsp;[<a href="r6rs-Z-H-21.html#node_bib_23">23</a>].</p>
